So, I'm having issues with my rig. 2 5970's and a 5830 via extension. They are unstable even when running stock everything (clock, memory, voltage) but with applying flags -v -w128. I don't believe it is a hardware issue.
Here are the details.
windows 7 64 bit
what happens is the cards will mine happily (at stock) for awhile but the screen would go black, and recover and the windows message (ati driver had some issue but recovered) and sometimes the entire system would just freeze.
When I first put the cards in, I anticipated relative ease as i've had with my other rigs so started them OC'd to 850 for each 5970 core and 900 for the 5830 core. (5970 stock core is 725 i think).
I've tried reinstalling catalyst a few times, and that doesnt work.
Any ideas? Whover is able to solve this for me i'd be happy to donate!!
